- Please think before printing the complete workbook; often lots of worksheets are not needed. In this case please print out only single worksheets

-If curves or righting moments are required, please fill in worksheets 6a and 6b or attach curve of righting moments for both loading conditions to the documentation.

- For boats with quick-draining cockpit the cockpit calculation according to ISO 11812 shall be enclosed to the documentation.

- Please attach other detailed information as appropriate, e.g. photos, sketches etc. for sill height, openings, companion way doors, location of flooding points, practical tests etc.

blue cells are derived valuesyellow cells require data input

- most worksheets have additional comments / remarks / other calculations beside the printout area; please take into account.

Please make sure to set your signature on the summary! (worksheet 16)either digitally or print summary, sign and attach scan

INFORMATION FOR OWNER'S MANUAL:Likelihood of capsize occuring in normal use:

Righting technique which is most successful:

Minimum number of crew required?

Is this time less than 5 min?

Minimum mass of crew required (kg):

Does boat float for > 5 min when fully capsized ?

Time required to right the boat (least time of 1 to 3 attempts)

With full Crew Limit aboard, without bailing, boat floats approx. level with at least 2/3 periphery showing, for more than 5 min ?

Design category recommended by the builder:

With one 75 kg person aboard, boat floats so it can be pumped or bailed out ?

ISO 12217-2:2015 CALCULATION WORKSHEET No.11 CAPSIZE-RECOVERY TEST

Design Categories C and D only

Is boat prepared as in 6.10.2 to 6.10.5 ?

Objective: to demonstrate that a boat can be returned to the upright after a capsize by the actions of the crew using their body action and/or righting devices purposely designed and permanently fitted to the boat, that it will subsequently float, and to verify that the recommended minimum crew mass is sufficient for the recovery method used.
